An anti-GMO website has posted the results of an education-based consulting company’s comparison of corn types, and the results reveal that genetically modified foods may be more hazardous than once thought.

The study, the 2012 Corn Comparison Report by Profit Pro, was published recently on the website for Moms Across America March to Label GMOs, a group that says they wish to “raise awareness and support Moms with solutions to eat GMO Free as we demand GMO labeling locally and nationally simultaneously.” They are plotting nationwide protests scheduled for later this year.

The report, writes the website’s Zen Honeycutt, was provided by a representative for De Dell Seed Company, an Ontario-based farm that’s touted as being Canadian only non-GMO corn seed company.

“The claims that ‘There is no difference between GMO corn and NON Gmo corn’ are false,” says Honeycutt, who adds she was “floored” after reading the study.

According to the analysis, GMO corn tested by Profit Pro contains a number of elements absent from traditional cord, including chlorides, formaldehyde and glyphosate. While those elements don’t appear naturally in corn, they were present in GMO samples to the tune of 60 ppm, 200pm and 13 ppm, respectively.
